I'm in to see what it makes. I'll be running a similar setup with a ported LS3 intake, Ported LS3 heads, and a GPI SS2 (which is similar to the TSP stage 2) on a bored LQ4 block. Mine will be going through an auto on a c5 with 3.15s and a Yank 3200 for now. I may have to use my free re-stall. We will see. I'm also looking to jump to 3.73s, but I'm holding off for now. I'm interested to see what you make. That will help me start to form my expectations. After bore and new pistons go in, my calculator is showing about 10.9:1 CR on my setup. What fueling setup are you running?
